555nm Optical Bandpass Filter with 30nm FWHM

This precision optical bandpass filter is designed to selectively transmit light centered at 555nm, with a Full Width at Half Maximum (FWHM) of 30nm. It provides a robust solution for applications requiring specific wavelength isolation within the visible spectrum.

Specifications:

• Central Wavelength: 555nm
• Full Width at Half Maximum (FWHM): 30nm
• Transmission Range: Effective transmission from approximately 540nm to 570nm, with peak transmission at 555nm.
• Blocking Range: Attenuates wavelengths outside the 555nm ±15nm range, ensuring reduced interference from non-targeted wavelengths.

Features:

• Enhanced Transmission: Optimized for high transmission efficiency around the central wavelength, ensuring accurate and clear signal capture.
• Advanced Coatings: Precision-coated to deliver high optical performance, durability, and minimal spectral distortion.
• High Durability: Constructed from premium optical materials for long-lasting performance and reliability in various environments.

Applications:

• Color Imaging: Ideal for applications in color imaging and analysis, where accurate detection and representation of colors around 555nm are essential.
• Light Measurement: Perfect for photometric studies and light sensors that require specific wavelength isolation to measure light intensity and color response accurately.
• Spectroscopy: Useful in spectral analysis where a defined wavelength band around 555nm is needed for precise measurement and data collection.
• Biological and Medical Research: Supports imaging and diagnostic applications where isolation of specific wavelengths enhances clarity and contrast.
